mb/qemu-{i440fx,q35}: reduce default ROM size to 8 MiB
By default, QEMU bails when trying to use bigger images mounted with
'-drive if=pflash', which is required to make use of writable flash
introduced in CB:82555. This changes both default size in Kconfig as
well as FMAP layouts.
Since QEMU 5.0.0 it is possible to change the limit of firmware size
with `max-fw-size` machine configuration option, up to 16 MiB, as bigger
sizes would overlap with IO APIC memory range. Default is still 8 MiB,
so it makes sense to have identical default in coreboot.
Error thrown by QEMU when trying to use too big ROM:
qemu-system-x86_64: combined size of system firmware exceeds 8388608 bytes
